Q:
Simplify.
\[ \left(7 t^{2}-2 t+6\right)+\left(-4 t^{2}+3 t+5\right) \]
Q:
Match the polynomial on the left with the appropriately factored expression on the right.
\[ \begin{array}{l}4(x-3)(x+4) \\ \begin{array}{l}x^{2}-7 x+12 \\ 4 x^{2}-13 x-12 \\ 4 x^{2}-4 x-48\end{array} \\ \begin{array}{l}(x-3)(4 x+3)(4 x+4) \\ (x-3)(x-4) \\ 4(x+3)(x-4)\end{array}\end{array} \]
Q:
Solve for \( x: 5^{x-1}=3\left(2^{x-1}\right) \)
Q:
Match the polynomial on the left with the appropriately factored expression on the right.
\[ \begin{array}{l}x^{2}-7 x+12 \\ \qquad \begin{array}{ll}\left.4 x^{2}-13 x-3\right)(x+4) \\ 4 x^{2}-4 x-48 & (x-4)(4 x+3) \\ (x-3)(4 x+4) \\ & (x-3)(x-4) \\ 4(x+3)(x-4)\end{array}\end{array} \]
